Protect a Wide Variety of Data
Circuits from ESD Damage
Introducing the Cooper Bussmann™ MLVA
and MLVB Series of Multilayer Varistors that
Protect Against ESD Damage in Discrete
0201, 0402 and 0603 SMD Packages
• Space Savings
Available in small SMD packages from 0201 to 0603, the discrete
designs of the Copper Bussmann™ MLVA and MLVB Series save
precious PCB space while giving designers flexibility in device
placement for superior ESD protection schemes.
• Low Capacitance MLVB Series
With low capacitances ranging from 0.5-5pF, the MLVB Series is ideal
for some high speed transient voltage protection, including USB 2.0.
• Low Leakage Currents
The MLVA and MLVB Series feature an insulator overcoat to keep
leakage currents low and stable.
• Fast Response Time
Both the MLVA and MLVB Series provide fast response time (<1ns),
allowing equipment to pass IEC 61000-4-2 Level 4 Test for ESD
protection.
• Environmentally Friendly
Cooper Bussmann offers ESD suppressors that are RoHS compliant,
lead free* and halogen free, making them a great choice for any
global application.

Design Considerations:
The location in the circuit for the MLVA and MLVB Series
has to be carefully determined. For better performance,
the device should be placed as close to the signal input as
possible and ahead of any other component. Due to the
high current associated with an ESD event, it is recommended to use a “0-stub” pad design (pad directly on the
signal/data line and second pad directly on common
ground).
